A member asked:
I am having a reaction to insect bites. i have extra strength benadryl (diphenhydramine) nighttime, 1 50mg pill isn't working can i take 2?
A doctor has provided 1 answer
Benadryl (diphenhydramine): 50mg is the recommended dose but adults can take 400mg in 24 hours. Take 50mg 30 minutes before bedtime and if not effective by 30 minutes repeat the dose. If this is making you drowsy the following day you know it is too much. Your size and weight may have a lot to do with your dose. All the best.
